Macroscopic Description: Carol Schwarz

The exterior surface of this small flat fragment is dark brown with a few mm-sized yellow and green mineral grains visible. Some evaporite is also present. The interior is dark brown, mostly metal, with yellow and brown crystals scattered throughout.

Thin Section (,2) Description: Brian Mason

This section shows plagioclase and pyroxene clasts, up to 1.2 mm across, in an opaque matrix of nickel-iron and troilite (the nickel-iron extensively weathered to limonite). Most of the pyroxene is hypersthene, with composition near Wo3Fs28, but one grain of augite, Wo40Fs27, was analyzed. Plagioclase composition is An91-96. One grain of tridymite was analyzed. The meteorite is a mesosiderite, and can be confidently paired with QUE86900.
